That sound insulating material 14 is the elastomer be made up of rubber or thermoplastic resin etc., that there is sound insulation property sheet material.Sound insulating material 14 is preferably polyvinyl chloride.Sound insulating material 14 is provided with 2 layers, is configured between each sound-absorbing material 11.Sound insulating material 14 has the thickness of about 1mm ~ 6mm.
Nonwoven fabric sheet 15 is sound absorption properties, the non-woven fabrics with the gas permeability of appropriateness that do not damage the sound-absorbing material 11 of fitting with this non-woven fabrics 15.Non-woven fabrics 15 is formed by polyester fiber, low melting point polyester fiber, polypropylene fibre, polyethylene fibre, Fypro, acrylic fiber, polyurethane fiber, polyvinyl chloride fibre, glass fibre etc.
This nonwoven fabric sheet 15 has anti-flammability.Nonwoven fabric sheet 15, by the coating organic series flame retardant material of infiltration (bromine compounds, phosphorus compound, chlorine compound), inorganic series flame retardant material (antimonial, metal hydride) and the flame-retardant materials disclosed in Japanese Unexamined Patent Publication 2006-83505 publication, can possess required anti-flammability.Anti-flammability is applied by the heat cured resorcinol system resin etc. making such as monohydric phenol and polyhydric phenols be formed and is infiltrated in non-woven fabrics and its heat cure is given.In addition, anti-flammability also can by giving containing flame retardant fiber.
Nonwoven fabric sheet 15 is containing thermosetting resins such as resorcinol system resins.Thus, utilize hot forming and be configured as target shape.Nonwoven fabric sheet 15 also has oil repellency, hydrophobicity.Oil repellency, hydrophobicity by so that make fluorine system hydrophobic and oleophobic agent etc. be infiltrated in nonwoven fabric sheet 15 and give.In addition, nonwoven fabric sheet 15 utilizes described thermosetting resin to be bonded to each other to the edge perimembranous 16 of major general's nonwoven fabric sheet 15.When cementability deficiency, the bonding agents such as hot-melt adhesive are applied according to manufacturing condition etc. at thermosetting resin.Bonding agent is polyethylene, polypropylene, polyolefin-based resins, polyvinyl chloride, polyurethane, polyester, polyamide, phenolic resins, epoxy resin etc., and these contain solution coating infiltration in non-woven fabrics.
Nonwoven fabric sheet 15 covers sound absorption and insulation sheet material 10, and the edge perimembranous 16 of nonwoven fabric sheet 15 is added thermo-compressed each other, and therefore, this nonwoven fabric sheet 15 has the size larger than sound absorption and insulation sheet material 10.That is, sound absorption and insulation sheet material 10 has the size less than the edge perimembranous 16 of nonwoven fabric sheet 15.In addition, nonwoven fabric sheet 15 has 50g/m

2the weight per unit area of left and right.
The acoustic material 1 be made up of so each component is integrally formed as described later under the state utilizing nonwoven fabric sheet 15 to cover two surfaces of sound absorption and insulation sheet material 10 respectively.Such acoustic material 1 preferably, is meeting the UL94V-0 of anti-flammability specification, the degree as the FMVSS302 of american car security criteria as Underwriters Laboratories Inc. defined with sound-absorbing material 11 compound tenses such as felts.
In addition, the compressor 2 using acoustic material 1 is provided with the distribution pipings such as bleed pipe, suction line or electric distribution.Therefore, acoustic material 1 has the through hole 18 and otch 19 that pass through for these distribution pipings of confession.Through hole 18 and otch 19 are also provided with the edge perimembranous 16 adding thermo-compressed.(or through hole 18 and otch 19 are arranged in edge perimembranous 16.)
Then, the making step of acoustic material 1 is described.
Nonwoven fabric sheet 15 and sound absorption and insulation sheet material 10 hot forming under stacked state.Now, the edge perimembranous 16 of nonwoven fabric sheet 15 adds mutually thermo-compressed and bonding.That is, sound absorption and insulation sheet material 10 is configured in than adding the edge perimembranous 16 of thermo-compressed in the inner part, and each sheet material of sound absorption and insulation sheet material 10 configures each other not fastened to each otherly.Thus, acoustic material 1 holds sound absorption and insulation sheet material 10 and directly forms as one in the bag-shaped nonwoven fabric sheet 15 of sealing.
In addition, acoustic material 1 is stamped to form as target shape.Specifically, be configured with the outermost layer of side of sound-absorbing material 11a, nonwoven fabric sheet 15 is to be shaped along the mode of the surface configuration formed by sound-absorbing material 11a and gap 12 (sound insulating material 14).Now, though nonwoven fabric sheet 15 and sound-absorbing material 11a or sound insulating material 14 bonding in relatively large area, need not be bonding energetically.
Through hole 18 and otch 19 are formed by using Thomson mould point mouth mould (ト system ソ Application type PVC Network type) stamping-out after such as hot forming.In addition, when using the situation etc. can carrying out shaping that is stamping and that cut cutting mould manufacture simultaneously in 1 operation, through hole 18 and otch 19 also can be formed when hot forming.In addition, the edge perimembranous 16 of through hole 18 and otch 19 is added thermo-compressed with the edge perimembranous 16 of the periphery of nonwoven fabric sheet 15 simultaneously.
As an object lesson, following method can be utilized very easily to manufacture acoustic material 1.
First, the lower pressurization disk of press is configured with forming jig.Heater is built-in with in this press.Forming jig has the shape corresponding with the thickness (highly) of the shape of edge perimembranous 16 and acoustic material 1.In addition, forming jig also has the shape corresponding with the shape in gap 12, thickness (highly).Forming jig both can be formed by multiple component, also can be formed by same component.Now, forming jig be heated to temperature that the bonding agent of infiltration in nonwoven fabric sheet 15 can be bonding, about 200 DEG C of such as resorcinol system resin solidification.
Stacked nonwoven fabric sheet 15, sound absorption and insulation sheet material 11, nonwoven fabric sheet 15 in order on this forming jig (lower pressurization disk).Nonwoven fabric sheet 15 is coated with the bonding agents such as hot-melt adhesive, the face of coating is configured in sound absorption and insulation sheet material 11 side in an overlapping manner.The mode that the face being configured in compressor 2 side when nonwoven fabric sheet 15 grade is to be arranged on compressor 2 is lower surface configures.Now, forming jig is configured with the edge perimembranous 16 of the crimping portion becoming nonwoven fabric sheet 15.The forming jig corresponding with edge perimembranous 16 does not configure sound absorption and insulation sheet material 11.In addition, forming jig is also configured in the position being formed with gap 12.
Then, the upper pressurization disk of press declines, and in utilization, nonwoven fabric sheet 15 crimps with required pressure by pressurization disk and forming jig.Thus, heat is transmitted to nonwoven fabric sheet 15 from upper and lower pressurization disk and forming jig, and the thermosetting resin of infiltration solidifies (utilizing hot-melt adhesive) each other, thus nonwoven fabric sheet 15 is bonded to each other.Now, preferably, the temperature of upper and lower pressurization disk is respectively 200 DEG C of front and back, and adding the thermo-compressed time is about 50 seconds.
In addition, in gap 12, nonwoven fabric sheet 15 is formed as the surface configuration along being formed by sound-absorbing material 11a and gap 12 (sound insulating material 14).Now, utilize the height etc. of forming jig to regulate, thus nonwoven fabric sheet 15 contact completely or partly with sound-absorbing material 11c with sound-absorbing material 11a, bonding.Afterwards, through hole 18 and otch 19 is made.
The acoustic material 1 made like this utilizes hot forming that each sheet material 10,15 is integrally formed.Thus, handwork need not be utilized aluminium foil, glass fabric to be rolled on felt as adopting such as aluminium foil in the past, the acoustic material of glass fabric that is made up of glass fibre etc.Thereby, it is possible to improve the manufacturing of acoustic material 1.In addition, even if when the position of through hole 18, shape are not simple, manufacture also transfiguration easy.In addition, when using described such forming jig hot forming, by being altered to shape, the configuration of clamp, the acoustic material 1 corresponding to the shape of compressor 2 can easily be manufactured.
In addition, by making nonwoven fabric sheet 15 self possess required anti-flammability, and utilizing the compound with the anti-flammability being configured in the sound-absorbing material 11 inside nonwoven fabric sheet 15, necessary anti-flammability can be guaranteed.Therefore, even if the outermost layer contacted with compressor 2 is non-woven fabrics, also can overall prevent by the oil of compressor 2 cause on fire.And, due to by reliably bonding for the edge perimembranous 16 of nonwoven fabric sheet 15, therefore, also can prevent the etch of oil or rainwater sound-absorbing material 11 internally, on fire, anti-deterioration (durability) and the sound insulation value of acoustic material 1 self can be maintained.In addition, when nonwoven fabric sheet 15 has oil repellency, hydrophobicity, described effect can be played further.
Further, because acoustic material 1 is only made up of the material with flexibility, therefore, easily install to compressor 2, also can improve workability.In addition, because the face contacted with compressor 2 is the nonwoven fabric sheet 15 with flexibility, therefore, the vibration (sound) caused by contacting between compressor 2 with acoustic material 1 can also be suppressed.
Nonwoven fabric sheet 15 (edge perimembranous 16) is solidified by adding thermo-compressed, but sound absorption and insulation sheet material 10 does not solidify and can maintain flexibility.Therefore, workability when installing to compressor 2 can not be reduced.In addition, due to sound absorption and insulation sheet material 10 each sheet material each other not bonding (fixing), therefore, when reeling to compressor 2 can with the correspondingly movement mutually of the circumferential lengths of each layer.Therefore, it is possible to improve workability when installing to compressor 2 further.
In addition, the sound absorption and insulation sheet material 10 shown in Fig. 1 ~ Fig. 3 also can be only made up of sound-absorbing material 11 layers, also can as shown in Figure 5 by sound-absorbing material 11 be 2 layers, sound insulating material 14 is 1 layer and forms.In addition, sound absorption and insulation sheet material 10 can be also more than 4 layers by sound-absorbing material 11, sound insulating material 14 is correspondingly more than 3 layers with the number of plies of sound-absorbing material 11 and forms.
In addition, nonwoven fabric sheet 15, the shape of sound absorption and insulation sheet material 10, thickness, the number of plies, through hole 18, the shape of otch 19, position, quantity is decided according to the shape of compressor 2 of installing for acoustic material 1, the sound insulation value of demand.Therefore, the acoustic material 1 etc. illustrated in the present embodiment is not limited to.
Further, in order to prevent in use procedure by the oil of compressor 2 cause on fire, also can be configured at the installation aluminum sheet at least partially of nonwoven fabric sheet 15 of compressor 2 side.Thereby, it is possible to provide the acoustic material 1 also can tackled higher fire line and require.As the method for installing aluminum sheet, the method that the operation that can be applied in described in utilization utilizes the bonding agents such as sealing to paste after making acoustic material 1, the method being thermally bonded in acoustic material 1 by lamination aluminum sheet such as polyethylene when hot forming.
Then, use embodiment to improve present embodiment acoustic material 1 sound insulation value and realize lightness and be described.In addition, the present invention is not limited to embodiment shown below.
